CGI - object rendering

I'm looking for someone with knowledge in CGI, tools like Blender and Camera Tracking and object tracking. [login to view URL] in this sample a monkey head is added in the background and an object is added in the woman hands. Two more samples: [login to view URL];feature=related [login to view URL];feature=related I need a similar footage, 30 seconds or less, and the objects that are added to the scene as ARGB images (png format). VOODOO can be used for camera tracking and Blender can be used to render the objects, for the same scene I need at least two types of objects rendered.
